EX15 · AC Power Requirements
AC Power
The EX15 uses a PowerCon 3-pole AC main system with locking connectors to prevent accidental disconnection.
The main AC connector (blue) serves as the power input.
The EX15 operates in either 115V, 230V or 250V modes. Although pre-configured at the factory, the unit's operating
voltage mode can be changed in the field.
Voltage Requirements
The EX15 operates safely and without audio discon - tinuity if the AC voltage stays within the operating window of
100V-120V in 115V mode, 205V-240V in 230V mode and 225V-260V when working in 250V mode, at 50 or 60Hz.
If the On LED does not illuminate or the system does not respond to audio input, remove AC power
immediately. Verify that the voltage is within the proper range. If the problem persists, please contact KV2
Audio or an authorized service center.
If the voltage drops below the low boundary of its safe operating range, the loudspeaker will shut down if the voltage
does not rise above the low boundary before storage circuits are depleted. How long the loudspeaker will continue to
function during brownout depends on the amount of voltage drop and the audio source level during the drop. If the
voltage increases above the upper boundary of the range, the power supply can be damaged.
It is recommended that the voltage supply be within the rated voltage window. This ensures that AC voltage
variations from the service entry- or peak voltage drops due to cable runs do not cause the amplifier to cycle on
and off or cause damage to the power supply.
For best performance, the AC cable voltage drop should not exceed 10 volts, or 10 percent at 115 volts and 5
percent at 230 volts.
Make sure that even with the AC voltage drop, the AC voltage always stays within recommended operating ranges. The
minimum electrical service amperage required by a EX15 speaker system is the sum of each loudspeaker's maximum
continuous rms current. An additional 50 percent above the minimum amperage is recommended to prevent peak
volt-age drops at the service entry.
The Power Connector
The EX15 requires a grounded outlet. It is very important that the loudspeaker AC supply be properly grounded in
order to operate safely and properly. Use the PowerCon AC cable-wiring diagram to create international or special-
purpose power connectors:
